Ann-Margret & Jaclyn Smith to "SVU"

Of course, Ann-Margret's greatest guest-starring role ever was on The Flintstones. Still, we are happy to hear that she is returning to TV once again for a guest spot on an upcoming episode of Law & Order: SVU.

According to TVGuide.com, the two-time Oscar nominee will play a star of '70s TV commercials. Jaclyn Smith will also star as a retired cop.

The two aren't the only actresses coming to the show's 11th season. Sharon Stone has a short run coming up. Also, Kathy Griffin and Mischa Barton will appear in back-to-back episodes in March.

Law & Order: SVU airs Wednesdays at 10:00 p.m. (EST) on NBC.
